I started in my kitchen with real quinine from real Peruvian trees, just like when tonic water was invented back in 1825. Then lightly sweetened it with agave nectar rather than loads of sugar so it complements rather than masks the subtleties of a good gin, vodka, or rum. And topped it off with extra carbonation so your drink stays fizzier longer. Clean and crisp, with 60% fewer calories than factor tonic waters, Q Tonic is a perfect match for great spirits. It will make your drink spectacular. Enjoy, Jordan Silbert, Founder. Imagine your favorite drink even better. A gin and tonic is mostly tonic. You love your favorite gin.

Her husband, the Spanish viceroy in Peru, begged the local Incas for an antidote. The Incas graciously gave her a potion from the ground bark of the native quinquina tree. Days later she was cured. In her honor, the Spanish renamed the Peruvian tree the cinchona tree. 200 years later, a few ingenious British officers in the Indian army improved the bitter quinine medicine by mixing it with soda, sugar, and gin. The original gin and tonic was born.
